To E.{Mr Elliott - Chief Engineer} from EFC. X.3362 RE LIGHTING INSTALLATION AT W.W. Your note to hand. I am sorry to hear that Mr. Royce is displeased with my efforts in this direction, but now I understand better what kind of fittings he requires. At first I did not realise that he would be particular and I thought the ordinary standard fittings would be quite suitable, in view of the fact that one of your earlier notes stated that a "rough and ready installation" was all that was required. However I will now make enquiries with a view to getting something more on the lines of a car lighting set. Re small switches, I think you must mean, when you say small brass switches 1.5" in diameter, what we call minature switches and I will send one of these for you to see if these are the switches to which you refer, if so it is quite easy to obtain these and I could have done so before except that I was under the impression that it was porcelain switches that were required. This does not, however, settle the matter of the main switches which have to carry up to 10 or 12 amperes. I have known these minature switches to get quite appreciably warm if the contact happens to be bad, on as low a current as 1 ampere. | ||
